Answer:

The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is: y=-x+3

Step-by-step explanation:

Given equation of line is:

[tex]y = x+2[/tex]

Comparing it with the general form of equation of line in slope-intercept form

[tex]y = mx+b[/tex]

The slope of given line is 1 as the co-efficient of x in the equation is 1.

When two lines are perpendicular, the product of their slopes is -1

Let m1 be the slope of new line

Then

[tex]m.m_1 = -1\\1.m_1 = -1\\m_1 = -1[/tex]

The equation of new line perpendicular to given line will be:

[tex]y = m_1x+b[/tex]

Putting the value of m1

[tex]y = -x+b[/tex]

To find the value of b, the given point will be put into the equation

So,

[tex]-1 = -(4)+b\\-1 = -4+b\\-1+4 = b\\b = 3[/tex]

The final equation of line is: y = -x+3

Hence,

The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is:

[tex]y = -x+3[/tex]

Graph:(Attached)

The graph is made using the online graphing tool "Desmos". The red line in the graph represents the line y = x+2 and the blue line represents the line (y=-x+3) perpendicular to given line

Answer: There are four and one-fourth cups of dry ingredients are in the cake mix.

Step-by-step explanation:

Given: Quantities of dry ingredients for cake:

2 cups of flour, [tex]\dfrac32[/tex] cups of sugar, and [tex]\dfrac34[/tex] cup of cocoa.

Total cups of ingredients used = [tex]2+\dfrac32+\dfrac34[/tex]

[tex]\dfrac{2\times4+3\times2+3}{4}\\\\=\dfrac{8+6+3}{4}\\\\=\dfrac{17}{4}\\\\=\dfrac{16+1}{4}\\\\=4\dfrac14\text{ cups}[/tex]

Hence, there are four and one-fourth cups of dry ingredients are in the cake mix.

Answer:

25.

Step-by-step explanation:

50% = 1/2 and 1/2 of 50 is 25. so 50% is 25.

Answer:

The answer is 25.

Step-by-step explanation:

This is actually very simple but other percentages would be harder. 50% s the same as 1/2 or 0.5. all you have to do is divide 50/2 which is 25. 25 is 50% of 50.

Answer:

So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.

Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.

Slope= (180-100)

          ----------------    = -2

          (960-1000)

Formula: y=-2(x-1000)+100

Part B: y=-2(980-1000)+100=140

140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.

Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.

Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

24/27=8/9

Step-by-step explanation:

Answer:

x ≥ 4

Step-by-step explanation:

-4(8 - 3x) ≥ 6x - 8

-32 + 12x ≥ 6x - 8

-32 + 8 ≥ 6x - 12x

-24 ≥ -6x

x ≥ 24 / 6

x ≥ 4

y =(x+ 1/2 ²- 25/4 . explanation. y=x²+x=6 . complete the square.

y=x²+x+(1/2)² -6 - 1/4 . simplify

y=(x+1/2²)- 25/4 in the vertex form

Answer:

The width is 20.625 and the length is 19.375

Step-by-step explanation:

Let 2 1/2 + w = length

Let w = width

Equation:

2 1/2 + w + w = 80                     Combine liked terms

2 1/2 + 2w = 80                    

-2 1/2         -2 1/2                        Subtract 2 1/2 from both sides

2w  =   77.5

÷ 2     ÷ 2                                    Divide 2 from both sides

w = 41.25

Length:

2 1/2 + 41.25 = 165/4 or 38.75

Width:

41.25

41.25/2 = 20.625

38.75/2 = 19.375

Step-by-step explanation:

This table represents the number of ounces, u, a kitten grows after w, weeks.

When graphed, all of the points in the table lie on the same line.

What is the slope and y-intercept of the line?

slope=−23, y-intercept=−0.2

slope=23, y-intercept=−0.2

slope=−32, y-intercept = 3

slope=32, y-intercept = 3

Weeks, w Weight in ounces, u

0 3

3 7.5

6 12

9 16.5

This doesn't seem like a academic question. The teacher is simply asking you how if you understand slope and graph of a line. Answer this of your own.

Answer:

? is 24

Step-by-step explanation:

Answer:

? = 24

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{?}{18}[/tex] = [tex]\frac{20}{15}[/tex] ( cross- multiply )

15? = 360 ( divide both sides by 15 )

? = 24

Answer: The length is 30, the 2 sides are 15.

Answer/Step-by-step explanation:

✅m<1 = 90° (right angle)

✅m<2 = 90° (<1 and <2 are supplementary, and also linear pair)

✅m<3 = 90° (<1 and <3 are supplementary, and also linear pair)

✅m<4 = 115° (vertical angles theorem)

✅m<5 + m<4 = 180° (linear pair)

m<5 + 115° = 180° (substitution)

Subtract 115 from each side

m<5 = 180 - 115

m<5 = 65°

✅m<6 = m<5 (vertical angles are congruent)

m<6 = 65° (substitution)

✅m<7 = m<1 + m<6 (exterior angle theorem)

m<7 = 90° + 65° (substitution)

m<7 = 155°

✅m<8 = 180 - m<7 (linear pair theorem)

m<8 = 180 - 155 (substitution)

m<8 = 25°

✅m<9 = m<7 (vertical angles are congruent)

m<9 = 155° (substitution)
